The testpack package

Haskell Test Utility Pack for HUnit and QuickCheck testpack provides
utilities for both HUnit and QuickCheck. These include tools for
running QuickCheck properties as HUnit test cases, allowing you to
combine both approaches in a single program. It also includes tools for
more helpful displays of running progress in both HUnit and QuickCheck,
additional generators for other types for QuickCheck, and shortcuts for
quickly defining new test cases.
